The Application and Limitation of Universal Chloroplast Markers in Discriminating East Asian Evergreen Oaks

open access: yesFrontiers in Plant Science, 2018
The East Asian subtropics mostly occupied by evergreen broad-leaved forests (EBLFs), is one of the global diversity centers for evergreen oaks. Evergreen oaks are keystone canopy trees in EBLFs with important ecosystem function and crucial significance ...

Mountainous vegetation succession and land use during the last millennium in the Peloponnese (southern Greece): Environmental change and economic development in an isolated periphery

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Mediterranean mountainous areas and their valuable natural resources have long been attractive to human societies. The Peloponnese (southern Greece), with its complex topographic and climatic variability, has been the scenery for the development of numerous human communities.

Female and male grizzly bears differ in their responses to low‐intensity recreation in a protected area

open access: yesThe Journal of Wildlife Management, EarlyView.
Human access and time of day affect the behavior (movement rate, selection) of grizzly bears (Ursus arctos) near recreation sites in a protected area. Males used trails to travel during crepuscular and nocturnal hours, especially in restricted areas, whereas females showed more cautious responses, suggesting security trade‐offs.

Spatial variation in local population dynamics of sika deer, Cervus nippon, through intensified management

open access: yesThe Journal of Wildlife Management, EarlyView.
We analyzed sika deer density trends over 27 years in 256 mesh‐units in Hokkaido, Japan. High‐density areas saw sharp declines, while low‐density areas remained stable. Prioritizing management in high‐density areas can improve overall control efficiency. Abstract Population reduction through hunting and nuisance control has been practiced in many parts

Effects of (Assisted) Natural Regeneration on Infiltrability and Preferential Flow Pathways in the Khasi Hills (Meghalaya, NE India)

open access: yesLand Degradation &Development, Volume 36, Issue 5, Page 1564-1578, March 2025.
ABSTRACT Intensified slash‐and‐burn cultivation and forest clearing have caused severe land degradation in the Khasi Hills (Meghalaya plateau, NE India). Despite very high annual rainfall, the region faces severe water scarcity during the dry season.

Linking Relationship of Ecosystem Service Supply and Demand Into Sustainable Development Goals (SDGs)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Ecosystem services (ES) play a crucial role in sustainable development. We systematically assessed the spatial and temporal dynamics of ecosystem service supply (ES‐s) and demand (ES‐d) in China from 1990 to 2020 by using a supply–demand matrix integrated with land use/cover data. The findings indicate that in 2020, grasslands accounted for 28.

Hydrological seasonality is a major driver of ecosystem metabolism in tropical nonwadeable rivers

open access: yesLimnology and Oceanography, EarlyView.
Abstract Studies of annual patterns of ecosystem metabolism in rivers have primarily been conducted in temperate ecosystems, and little is known about metabolic regimes of tropical rivers. We estimated ecosystem metabolism in four nonwadeable rivers in southern México that varied in size and the extent of human disturbance.

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

open access: yesLimnology and Oceanography, EarlyView.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.
